Usage Hints

Check that default values in Settings meet your needs (touch item titles for help).
Then in Accounts, create one or more accounts (again touch item titles for help).
Registration status of an account is shown with a colored dot: green (registration succeeded, yellow (registration is in progress), red (registration failed), white (registration has not been activated).
Swipe down gesture causes re-registration of the currently shown account.
Peers of calls and messages can be added to contacts by long touches.
Long touches can also be used to remove calls, chats, messages, and contacts.
Touch/long touch of contact icon can be used to install/remove image avatar.
You can re-reselect the previous call party by touching the call icon when Callee is empty.
If you cannot hear the other party during call, try to increase Media volume of the device or set Default Call Volume in Settings.

Known Issues

Due to limitations in underlying libraries, baresip does not currently support multiple, concurrently active network interfaces.

Invalid Display Name \'%1$s\' Authentication Username Authentication username if authentication of SIP requests is required. Default value is account\'s username. Invalid Authentication Username \'%1$s\' Authentication Password Authentication Password up to 64 characters. If Authentication Username is given, but Password is not given, it will be asked when baresip is started. Invalid Authentication Password \'%1$s\' Outbound Proxies SIP URI of one or two proxies that must be used when sending requests. If two is given, REGISTER requests are sent to both and other requests are sent to one that responds. If no outbound proxy is given, requests are sent based on DNS NAPTR/SRV/A record lookup of callee URI hostpart. If hostpart of SIP URI is an IPv6 address, the address must be written inside brackets []. \nExamples: \n • sip:foo.com:5060;transport=tls \n • sip:[2001:67c:223:777::10]:5060;transport=tcp SIP URI of Proxy Server SIP URI of another Proxy Server Invalid Proxy Server URI \'%1$s\' Register If checked, registration is enabled and REGISTER requests are sent at 12 minute intervals. Audio Codecs List of supported audio codecs in priority order Video Codecs List of supported video codecs in priority order Media NAT Traversal Selects media NAT traversal protocol (if any). Possible choices are STUN (Session Traversal Utilities for NAT, RFC 5389) and ICE (Interactive Connectivity Establishment, RFC 5245). STUN/TURN Server A STUN/TURN Server URI of form scheme:host[:port], where scheme is \'stun\', \'stuns\', \'turn\', or \'turns\'. Factory default STUN server is \'stun:stun.l.google.com:19302\', pointing to public Google STUN server. There is no factory default TURN server.

Prefer IPv6 Media If checked, offer to use IPv6 media protocol (if available) when media protocol of peer cannot be automatically determined. Answer Mode Selects how incoming calls are answered. Manual Automatic Voicemail URI SIP URI for checking of voicemail messages. If left empty, voicemail messages (Message Waiting Indications) are not subscribed to. Invalid Voicemail URI \'%1$s\' Default Account If checked, this account is selected when baresip is started. Accounts New Account Account\'s port number and transport protocol may be optionally given when a new account is created: username@domain[:port][;transport=udp|tcp|tls]. If port is given and transport protocol is not given, transport protocol defaults to udp. If port is not given and transport protocol is given, port defaults to 5060 or 5061 (TLS). If neither is given and no outbound proxy is specified, account\'s registrar (if any) is determined solely based on domain\'s DNS information. user@domain Invalid user@domain[:port][;transport=udp|tcp|tls] \'%1$s\' Account \'%1$s\' already exists.

Listen Address IP address and port of form \'address:port\' at which baresip listens for incoming SIP requests. If IP address is an IPv6 address, it must be written inside brackets []. IPv4 address 0.0.0.0 or IPv6 address [::] makes baresip listen at all available addresses. If left empty (factory default), baresip listens at port 5060 of all available addresses. Invalid Listen Address 0.0.0.0:5060 DNS Servers Comma separated list of addresses of DNS servers. If not given, DNS server addresses are obtained dynamically from the system. Each DNS address is of form \'ip:port\' or \'ip\'. If port is omitted, it defaults to 53. If ip is an IPv6 address and also port is given, ip must be written inside brackets []. As an example, list \'8.8.8.8:53,[2001:4860:4860::8888]:53\' points to IPv4 and IPv6 addresses of public Google DNS servers.
